I think I'd trench in PVC electrical conduit (what you can by machine), woods by hand, and pull in THHN.
220/230/240 vac is a must.
I have considered a similar thing although my situation is not as complicated with only about 100 feet of run and 20 feet of rise, tanks are available in many capacities at
water tanks, plastic tanks, septic tanks with shipping estimates too. I think the black tanks are preferred to prevent algae growth.
One thing I can say is the system isn't cheap...one can use a lot of city water for what the wiring/pump/pipe/tank/pump system is going to cost. The only advantage I see is that you can probably then setup an irrigation controller and a bank of valves...yes, adding to the cost, but then watering is completely hands-off.
The other alternative might be to do this in stages, in other words, find a pump that will lift 40' and put the tank there, then a second pump to raise the rest of the way and also supply working water pressure. Depending on what the slopes are this may or not make sense.
On edit, the water ram, while simple, seems like it's not a good fit. The water ram requires potential energy of water falling to make the machine run, ala a waterfall (or a dam to artificially build potential energy...but that violates the OP's constraint of not damming up the creek). The bigger the waterfall, the more flow that can be achieved, if you look at the equation. One could theoretically use water from the uphill tank above to get it started, but since you lose 7 gallons out the discharge port for every gallon pumped...the uphill tank is going to empty a lot faster than its going to fill. Next possibility is to use an electric pump to drive the ram but I think it is going to end up less efficient to use the ram than just running the pump output directly uphill. Sadly, there aren't any perpetual motion machines...yet
